Twenty-five miles away from Mosul, Iraq, students in Khazer Camp go to school every day in tents. They lack textbooks or pens to write with, but they're just grateful to be learning. They, along with an estimated 1.4 million other Iraqi children, are displaced from their homes.

President Trump's proposed budget, which includes deep cuts to foreign aid, has some humanitarian organizations worried about the impact on displaced persons worldwide.

Under Trump's budget plan, the Department of State -- which funds the U.S. Mission to the United Nations -- faces cuts of nearly 29 percent.

This was a promise made to the American people and a goal to restore trust and value at the U.N.

Critics charge the U.N. spending cuts could lead to more global instability -- at a time when the world is facing its greatest humanitarian crisis since World War II.

But Nikki Haley, U.S. Ambassador the U.N., said the U.S. contributes already "disproportionate" amount to the organization.

The United Nations' refugee agency, UNHCR, says it needs at least $578 million to help displaced Iraqis in 2017. So far, it's 18 percent funded. When funding falls short, UNHCR's Ron Redmond says "excruciating decisions" have to be made on the ground about who to help.

UNICEF, the U.N. agency which works to improve the lives of children around the world, says it needs $161.4 million in donations to meet the basic needs of Iraqi kids in 2017. To donate, click here.
